SAW-SETTING DEVICE.

Application filed December 30, 1813.

To all whom it may concern:

Be it known that 1, Nine OLAF HEDMAN, a citizen of Sweden, residing at Leadville, in the county of Lake and State of U010- rado, have invented certain new and useful Improvements in Saw-Setting Devices, of which the following is a specification.

The present invention relates to improvements in saw setting devices and has for its primary object the provision of a. tool of this character that may be easily manipulated and susceptible of adjustment to accommodate difierent thicknesses or gages of saws as well as embodying teeth setting members readily adjustable to regulate the degree of set imparted to the saw teeth.

In carrying out my invention it is contemplated to employ a relatively stationary body portion with which a relatively movable body portion cooperates, which body portions carry the teeth setting members, one of which consists of an anvil having positive connection with the relativelymovable body portion, and means for adjusting the anvil on its carrying member, together with means for limiting the extent of adjustment of said anvil.

For a full understanding of the present invention, reference is to be had to the following description and the accompanying drawing, in which the figure illustrates a side elevation of an embodiment of my invention, a portion of the same being shown in section to bring out more clearly the details of construction.

Specifically describing my device, the numeral 1 represents a relatively stationary body portion which may be suitably connected to any desired supporting means. such as designated by the numeral 2, said body portion terminating preferably in a handle member 3 at its lower extremity.

The character 4: designates a relatively movable body portion which is connected to the relatively stationary body portion 1 for adjustment with respect thereto. This adjustment connection just mentioned is formed by the provision of an internally threaded sleeve 5 located at one side of the member 4 and which is mounted in a socket 6 formed in the corresponding side portion of the relatively stationary body portion 1 of the device. Projecting through said stationary body portion from beneath the same is disposed an adjusting screw 7 extending into the Specification of Letters Patent.

Serial No. 809,566.

threaded sleeve 5, having swiveled connection with the body portion as indicated at7 to prevent lengthwise movement, adaptedto actuate the member 4 so as to move the same toward or from the relatively stationary body portion 1. This movement is designed for the purpose of accommodating saws of different gages which are adapted to be introduced between the jaws 4: and 5 of the body portions 4 and 1 respectively. It is furthermore contemplated to form the movable member 4: adjacent the sleeve 5 with a depending flange 8 adapted to co-act with the outer surface of the adjacent portion of the stationary body portion 1, this flange acting as a guide as will readily be understood by reference to the figure of the drawing. The flange 8, moreover, tends to make more rigid and solid the connection of the movable member 4 with the stationary member 1.

Mounted in the relatively fixed body portion 1 for vertical reciprocation is a tooth setting punch or plunger 9 having operative connection at one end-with a lever or handle 10 which is pivotally mounted adjacent said plunger on the body portion 1 and adapted to reciprocate the plunger 9 when. grasped by the hand of the operator in conjunction with the handle 3. Disposed between the handle 3 and the lever 10 is a suitable leaf spring 11 tending to hold the plunger 9 in its normal retracted position. The plunger 9 carries at its opposite end to that above mentioned as connected with the lever 10, a removable head 12 having the face 12 formed at a suitable angle and designed to cooperate with the anvil 13 which is carried by the relatively movable body portion 4 of the device. It will be clearly noted from the drawing that the anvil 13 is mounted for pivotal movement on the pivot l-l within a recess 15 and said anvil comprises the arm 16 having an angularly formed face adapted to co-act with the face 12 of the head 12 of the plunger 9 for setting the saw teeth. It is noted that the pivotal mounting of the anvil as above described permits of movement of the arm 16 so as to present a dilferent angle to the head 12 whereby saws of varying length teeth, and consequently of varying degrees of set may be properly operated upon by the same implement. A. set screw 17 is threaded into the movable member f at a point permitting the same to extend into the recess 15 and into contact with the arm 16 of the anvil;

By movement or adjustment of this set screw said anvil may be moved on its pivot to change the degree of angularity of the face of said arm for presentation to the head 12 of the plunger 9. When the anvil has been adjusted in the manner described v the set screw 18 passing in a similar manner to the screw 17 through the member 4 into the recess 15 is adjusted so as to contact with the lever 19 projecting from the anvil 13 in a direction opposite to the arm 16. The purpose of this set screw in its 'coiiperation with the level-19 is to limit the movement or make rigid the adjusted position of the anvil, and it will be apparent that a wide range of adjustment may be provided for saw teeth by the peculiar mounting of this member.

It is contemplated in the manufacture of my device to provide a set or plurality of removable heads 12 each having a face 12 of different degree of angularity inorder to properly co-act with the angular adjustment of the anvil arm 16.

As shown in the drawing the support 2 consists of a slotted arm which is secured to a bench or wall in the manner. indicated,

and I preferably employ a vertical restor 'be apparent the vertical rest 20 is adjustably secured on the armor support 2 to permit relative movement of the same with respect to the saw set carried at the extremity of the arm.

Having thus described theinvention what is claimed as new is:

In a saw set, the combination of a .relatively stationary body portion, a movable body portion, and means for, actuating the latter to move the same with respect to the stationary body portion, said means comprising a set screw extending into the stati onary body portion, the movable bodyportion having a sleeve into which said set screw project said movable body portion also having an integral guide member spaced from the sleeve aforesaid and-adapted to cooperate with the relatively station- H.
